Could you please any one help on this

Look at the script.  The error occurs in line 3.

Hi,

Please run Get-Host in EMS to check PowerShell verison. If it's 1.0, please install PowerShell V2 for testing.

Because the parameter declaration in the function is a PowerShell V2 advanced function parameter declaration. For your reference: https://support.microsoft.com/en-us/kb/968929
